LS Eco Energy said on the 7th that its Vietnam manufacturing subsidiary LS-VINA has begun international certification and PQ (pre-qualification) for 400 kV ultra-high-voltage cables and will move to commercialization.
PQ is a key procedure that evaluates the long-term stability of the entire system on the premise of actual transmission grid application, and is considered a prerequisite for winning bids in large global transmission grid projects.
The 400 kV ultra-high-voltage cable will undergo about a year of product performance verification and long-term operational reliability assessment, then enter mass production in the second half of next year.
Once this project is completed, LS Eco Energy will also secure an ultra-high-voltage portfolio on par with LS Cable & System headquarters. LS-VINA currently produces up to 230 kV, while 400 kV has been a flagship ultra-high-voltage product line produced by LS Cable & System.
The 400 kV cable enables long-distance, high-capacity transmission and is used in large industrial complexes, AI data centers, and offshore wind and solar interconnection networks. Global demand is also growing rapidly as rising power demand from data centers worldwide coincides with the replacement of aging power grids in the United States and Europe and investments in grid expansion.
LS Eco Energy recently secured U.S. certification for 230 kV cables, laying the groundwork for market entry. If it also secures PQ for 400 kV, the company expects to be able to participate in bids for major global transmission grid projects, further strengthening its competitiveness.
An LS Eco Energy official said, "Entry into the 400 kV segment will serve as a catalyst to accelerate a shift to a business structure focused on revenue, along with expansion into advanced markets."
